Business people have the skills to solve

(a) All social problems

(b) Some social problems

(c) No social problems

(d) All economic problems

Business people do not have the skills to solve social problems. Businesspersons do not solve social problems because they are trained to handle business-related problems, such as minimising cost, maximising profits and increasing the volume of sales, and not social problems. Thus, in this regard, it is often argued that social problems must be solved by specialised agencies that have the required training and skills to do so.

Hence, the correct answer is option (c).
